Problem is with em0-em13 that many share an IRQ 16/17, and because I was using 6.2-p8 and therefore did not have MSI enabled/available. Polling was also not compiled into the kernel. Polling alone will give times between 0.2 and 1.3 ms (with HZ=1000), and MSI alone (after activated during boot within loader.conf) will give best results (around 0.4 to 0.5 ms for a ping through firewall and back across two lans). This was then with 6.3-p1 Still, 6.3-p1 without msi and polling is still very slow in handling IRQs from the em-nics. I still don't know exactly why this took up to 1.5 seconds (sometimes even more) without MSI or POLLING. Please see my previous emails for dmesg. pciconf -l gives: [EMAIL PROTECTED]:4:0: class=0x020000 card=0x11998086 chip=0x10b58086 rev=0x03 hdr=0x00 [EMAIL PROTECTED]:4:1: class=0x020000 card=0x11998086 chip=0x10b58086 rev=0x03 hdr=0x00 [EMAIL PROTECTED]:6:0: class=0x020000 card=0x11998086 chip=0x10b58086 rev=0x03 hdr=0x00 [EMAIL PROTECTED]:6:1: class=0x020000 card=0x11998086 chip=0x10b58086 rev=0x03 hdr=0x00 [EMAIL PROTECTED]:0:0: class=0x020000 card=0x10a48086 chip=0x10a48086 rev=0x06 hdr=0x00 [EMAIL PROTECTED]:0:1: class=0x020000 card=0x10a48086 chip=0x10a48086 rev=0x06 hdr=0x00 [EMAIL PROTECTED]:0:0: class=0x020000 card=0x10a48086 chip=0x10a48086 rev=0x06 hdr=0x00 [EMAIL PROTECTED]:0:1: class=0x020000 card=0x10a48086 chip=0x10a48086 rev=0x06 hdr=0x00 [EMAIL PROTECTED]:0:0: class=0x020000 card=0x10a48086 chip=0x10a48086 rev=0x06 hdr=0x00 [EMAIL PROTECTED]:0:1: class=0x020000 card=0x10a48086 chip=0x10a48086 rev=0x06 hdr=0x00 [EMAIL PROTECTED]:0:0: class=0x020000 card=0x10a48086 chip=0x10a48086 rev=0x06 hdr=0x00 [EMAIL PROTECTED]:0:1: class=0x020000 card=0x10a48086 chip=0x10a48086 rev=0x06 hdr=0x00 [EMAIL PROTECTED]:0:0: class=0x020000 card=0x108c15d9 chip=0x108c8086 rev=0x03 hdr=0x00 [EMAIL PROTECTED]:0:0: class=0x020000 card=0x109a15d9 chip=0x109a8086 rev=0x00 hdr=0x00 We have one quad PCI-X 64bit card (the first four) and two quad PCI-Express cards.
